Just curious if anyone has had their Minitor V not give the Low Batt Alert (red LED blink and a beep). Mine just cycles back through the self test.
A couple of things you can do....
First, make sure that the battery is firmly seated and the little latch is fully set. I'd suggest releasing the latch and slide the battery out. The slide it in and out several times to wipe the contacts clean. Then fully seat it and make sure it is fully latched.
Second, make sure the contacts on the bottom of the pager are clean. You may have to use a tooth pick to get the lint out of each hole. Then fully seat the pager in the charger and remove it several times. Again, that should help the pins wipe the contacts clean.
Occasionally, my charger will show a green light (fully charged) after just a couple of minutes. I remove the pager and replace it. Then it goes through a normal charge cycle.
These batteries are not supposed to develop chemical memory like the old nicads. However, at least one my squad members has had a battery fail recently. He tells me it will barely hold a charge for a day.
